In 2004, Green Party presidential candidate David Cobb was on the ballot in states containing 54.3% of the national presidential vote cast that year. In the places where he was on the ballot, he received .177% of the total vote cast in those places.
In 2008, Green Party presidential nominee Cynthia McKinney was on the ballot in states containing 69.7% of the national presidential vote cast that year. In the places where she was on the ballot, she received .173% of the total vote cast in those places.
Thus, the experience in these two presidential elections for the Green Party almost perfectly matches the Nader experience. In both cases, the candidate did a far better job of getting on ballots in 2008 than in 2004. But, in the areas with ballot status, the percentage of the vote received was virtually the same in both years.
